Ditra and control joints?

Evening all! I'm getting ready to tile a basement slab prepping with good old Ditra. There is a control joint running right through the middle of the floor.
Standard bath floor, approx 40 sq ft. And using 12 x 12s. I know they say to honor the joint into the assembly,but should I Ditra straight over the joint, not filling it with thin set of course, and then create a silcone "soft" joint in the nearest grout joint? Or do I slice the Ditra on the joint, then tile around it, as intentionally use it as a joint, despite possible better layouts,then stuff backer rod then silcone for the soft joint. Oh, joint looked to be parallel with door.
Movement joints always seem to confuse me. I understand why they are needed, just not sure how to approach carrying them through

Appreciate any tech on this, hope my explanation makes sense!

Go Broncos!

I would recommend reading and following the manufacturer's instructions on that, Norm.

Page 21 of their online handbook.

Thanks CX! Dang you are on it!! It says Ditra straight over the joint but add a soft joint as described in recommendations. So, since this is only 40 sq ft and not 400 I might not need one at all! Still kinda vague IMHO.
Thanks again

Hi Norm,

It's an unusual situation you have. Tough call, really. If it's your house, go for it. If it's for a customer, explain it and give the customer the option.

Norm, I was burned by this same dilema years ago on a less-than 30sf basement bath. I thought 'where could it possibly go in a bath that small?', but it cracked right through the grout.
Btw, the footage & size guidlines for tile control joints do not apply to concrete control joints. If you want to technically follow the rules, you have to always honor them in the tile above, no matter how small. If it's your own house though, you are really only risking an afternoon's work to later grind out a grout joint & replace it with a soft joint.

And here's a good example of what happens when a control joint in the concrete is not honored thru the tile assy

Holy crap!! That's no joke! Is that floor on Ditra as well?
So can I just add a soft joint closest to the control joint or should I break the tile on tha joint? I've already prepped the homeowners for the soft joint, now just need to figure placement I guess. Thanks bros hoe you all are staying busy!

I highly doubt it's on ditra Norm. Convenience store chains won't usually fork out that kind of $$. Personally I would have adjusted the layout so that a grout joint was directly over the control joint in the slab and made that the soft joint. Either that or just cut the tile at the control joint and added another grout joint - a soft joint of course.

As you can see the layout left lots to be desired.

Thanks Chad! Do you get into commercial stuff much? Not me, seems here in Denver, the few commercial jobs I've done we're always nuts! As in trades on top of eache other! Usually doesn't pay well so it has to just be done, no time for done right. I've actually had drywall guy sanding over my head into my wet mud! needless to say I have to be pretty hungry to take up a commercial gig. I also hate night work and hoping I get paid in three months!!
